WINDOW-SASH-OPERATING MECHANISM.

I To all whom it may concern: 1

a citizen of the United States, residing at Algiers, in the parish ofOrleans and State of Louisiana, have invented certain new and usefulImprovements in Window-Sash-Operating Mechanisms; and I do herebydeclare the following to be a Full, clear, and exact description of theinvention, such as will enable others skilled in the artto which itappertains to make and use the same. I

This invention relates to operating mechanism for the upper and lowersashes of a window, and an object of the invention is the provision of anovel form of mechanism of this character that will admit of thesimultaneous movement of both sashes either to Open or closed position.

Another object of he invention is the provision of operating mechanismfor ad-. mitting of the above object being carried out, and which hasassociated therewith a novel form of locking mechanism that can be movedto releasing position only from the inner side of the window.

Other objects will appear and be better understood from that embodimentof my invention of which the following is a specification, referencebeing had to the accompanying drawing forming a part thereof, in which:

Figure 1 is an inner side view of a window, having one side thereof insection, so as to show the operating mechanism,

Fig. 2 is a section taken on the line 22 of Flg. 1,

Fig. 3 is a section taken on the line 3-3 of Fig. 1,

Fig. 4: is a section taken on the line M of Fig. 2, I

Fig. 5 is a section taken on the line 55 of 2.

Re erring to the drawing in detail, the

letter A designates a window frame having mounted therein a upper sashC.

Mounted in one side of the window frame A is a pair of spaced verticalshafts 1 and 2, the said shafts l and 2 being of a length co-equal withthe height of the window frame and have their upper and lower endsjournaled, respectively, in bearings 3 and 4 located in the upper andlower sides of the window frame, as shown more particularly in Fig, 2 ofthe drawing. The shaft 1 passes through a vertical recess 5 formed inSpecification of Letters Eatent.

Application filed November 11, 1916. Serial No. 130,894.

the adjacent side of the lower sash B, and the shaft 2 extends through asimilar recess formed in the adjacent side of the upper sash G. Theshaft 1 is'provided with a spiral 'groove 6, which passes around theshaft and extends throughout the length of the shaft, and the shaft 2 issimilarly pro vided with a groove 7, which extends throughout the lengthof the shaft 2, and around the shaft 2 in the same direction in whichthe groove 6 extends around the shaft 1, as shown in Fig. 2 of thedrawing. Located within the recess 5 in the lower sash B is an elongatedplate 8, which extends throughout the length of the groove 5 and engagesthe inner wall of the groove and has its upper and lower terminals bentand extended at right angles to provide attaching flanges, which aresecured, respectively, to the upper and lower sides of the window sashB. The plurality of laterally extending spaced ting rs 9, which engagein the spiral groove 6 in the shaft 1. When movement is imparted to thelower sash B the fingers 9 will travel in the spiral groove 6 in theshaft 1 and effect rotation of the latter. per'end of the shaft 1 isprovided'with a gear Wheel 10, which meshes with a similar gear 11mounted on the upper end of the shaft 2. When the shaft 1 is rotated theintermeshing gears 10 and 11 will be rotated and rotation will beimparted to the shaft 2. A plate 12 is mounted within the recess formedin the upper sash C and The upplate 8 is provided with a extendsthroughout the length of the recess like the plate 8, is provided with aplurality of laterally exten ing and. spaced fingers, the said fingerson the plate 12 being designated by the numeral 13 and are received bythe spiral groove 7 formed in the shaft 2. When the lower sash B israised upwardly, rotation will be imparted to the shaft 1, and by virtueof the gears 10 and 11, the shaft 2 will receive rotation in a directionopposite to the direction of rotation of the shaft '1, and by reason ofthe fact that the groove 7 in the shaft 2 extends around the shaft 2 inthe same direction in which the gers 13 on the plate -12 will traveldownwardly in the groove 7 and efiect lowering of the upper sash C.Likewise,a downward movement of the lower sash B will cause the shaft 1to rotate in the opposite direction, 5 which in turn will, through themedium of the gears and 11 rotate the shaft 2 in that direction in whichthe fingers 13 on the plate 12 will be caused to travel upwardly in thegroove 7 and effect raising of the upper sash C.

A ratchet 14 is mounted on the lower end of the shaft 1 and is keyedthereto for rotation with the shaft 1, and the said ratchet rotates in arecess 16 formed in the lower side of the window frame, the said recesscommunicating with an elongated recess 17, which opens into the innersurface of the lower side of the window frame. A lever 18 is pivotedwithin the recess 17 and has one end pointed and extended into therecess 18 :and adapted to interchangeably engage the teeth of theratchet 14c. The inner end of the lever normally held in engagement withthe ratchet through the employment of 25 a s iding 19 which is mountedon one wall of the recess 17 and bears against the outer of the lever18. The terminal of the end of the lever 18 extends beyond the face ofthe lower side of the winme and serves as a manipulating "on to :1. dmitof the convenient operation or the le er if; when it is desired towithdraw the lever from engagement with the et lei. l'ly virtue of theprovision of ratchet 1% and lever 18, the window .oaiSllQS B and C canhe held at any point sired, within the indow frame; also when the windowsashes and C are moved to closed position. and the lever 18 engages theratchet, it will be impossible for the window sashes B and (J to hemoved to open position from a point exterior of the building.

it is evident that various changes might be resorted to in theconstruction, form and arrangement of the several parts withoutdeparting from the spirit and scope of the invention as claimed.

What I claim is: r

1. The combination with the movable upper and lower sashes of a window,of shafts located adjacent the respective sashes and operativelyconnected for rotat' in opposite directions and having sp groovesthereon, and means associated with each sash for engaging in the groovein the adjacent shaft, whereby upon movement of. either sash in onedirection by force applied directly to that sash movement will beimparted to the other sash in the opposite direc-tion,

It (id- 2. The combination with the movable sashes of a window andshafts located adjacent the respective sashes and operatively connectedfor rotation in the opposite directions and having spiral groovesthereon, of plates mounted on the sashes, and fingers carried by theplates and engaging in the grooves in the shafts so that when eithershaft is moved in one direction by force applied directly to that sash,movement will be imparted to the other sash in the opposite direction.

3. The combination with the movable sashes of a window, of shaftslocated adjacent the respective sashes and operatively connected forrotation in opposite directions, means associated with each sash andoperatively engaging the adjacent shaft so that upon movement of eithersash in one direction by force applied directly to that sash movementwill be imparted to'the other sash in the opposite direction aratchetcarried by one of the shafts, and means for interchangeablyengaging. the teeth of the ratchet so as to normally hold thelast-mentioned shaft against rotation, for the purpose specified.

4. The combination with the movable up- .per and lower sashes of awindow, of a pair of shafts located at one side of the window casing andoperatively connected for rotation in opposite directions and havingspiral grooves therein, and means associated with each sash for engaginin the groove in the adjacent shaft, where y the movement of one sash byforce applied directly to that sash will impart movement to the othersash in the oppositedirection.

5. The combination with a window casing, of upper and lower sashesmovably mounted therein and each having a vertical recess located in oneside thereof and extending throughout the entire length thereof, a pairof spirally grooved shafts journaled within the casing at one sidethereof and extending through the recesses in the sashes, plates equalin length to the length of the sashes and located within the recessesand secured to the sashes, a row of relatively spaced fingers extendingthroughout the entire length of each plate and engaging in-the groove oftheir respective shafts, and a pair of intermeshing gears fixed to theupper ends of the shafts.

In testimony whereof I aifix my signature in presence of two witnesses.
